In heterogeneous wireless networks supporting multi-access services, selecting the best network from among the possible heterogeneous connections and providing seamless service during handover for a higher Quality of Services (QoSs) is a big challenge. Thus, we need an intelligent vertical handover (VHO) decision using suitable network parameters. In the conventional VHOs, various network parameters (i.e., signal strength, bandwidth, dropping probability, monetary cost of service, and power consumption) have been used to measure network status and select the preferred network. Because of various parameter features defined in each wireless/mobile network, the parameter conversion between different networks is required for a handover decision. Therefore, the handover process is highly complex and the selection of parameters is always an issue. In this paper, we present how to maximize network utilization as more than one target network exists during VHO. Also, we show how network parameters can be imbedded into IEEE 802.21-based signaling procedures to provide seamless connectivity during a handover. The network simulation showed that QoS-effective target network selection could be achieved by choosing the suitable parameters from Layers 1 and 2 in each candidate network.

The genetic variability of three poultry breeds namely Aseel, Miri and Nicobari taken from different geographical locations of India were evaluated using 15 microsatellite loci. No. of alleles varied from 3 to 9 in Aseel, 3 to 8 in Miri and 2 to 7 in Nicobari. Mean PIC values in Aseel, Miri and Nicobari breeds were 0.64, 0.66 and 0.63, respectively. Average unbiased heterozygosity and direct count heterozygosity were 0.65 and 0.59, 0.68 and 0.61, and 0.64 and 0.57 in Aseel, Miri and Nicobari breeds, respectively. High heterozygosity values revealed in this study are indicative of low level of inbreeding, large population size and no or low selection pressure for commercial trait in all three populations. The estimate of genetic distances using Nei's standard, Nei's minimum and Reynold's distance revealed Aseel and Nicobari to be more closely related than Miri breed of poultry.

Genetic variation at 25 microsatellite loci, population structure, and genetic bottleneck hypothesis were examined for Ankleshwar poultry population found in Gujrat, India. The estimates of genetic variability such as effective number of alleles and gene diversities revealed substantial genetic variation frequently displayed by microsatellite markers. The average polymorphism across the studied loci and the expected gene diversity in the population were 6.44 and 0.670짹0.144, respectively. The population was observed to be significantly differentiated into different groups, and showed fairly high level of inbreeding (f = 0.240짹0.052) and global heterozygote deficit. The bottleneck analysis indicated the absence of genetic bottleneck in the past. The study revealed that the Ankleshwar poultry breed needs appropriate genetic management for its conservation and improvement. The information generated in this study may further be utilized for studying differentiation and relationships among different Indian poultry breeds.
In vivo glycorandomization in E. coli for natural product diversification

Stabilization, detoxification, and solubilization of small molecules based therapeutics and natural products can be altered by glycosylation. In vitro glycosylation of small molecules is difficult to scale up as well as costly to implement in industrial level. To overcome these hurdles, Escherichia coli has been engineered by heterologous overexpression of TDP-4-amino-4, 6-dideoxy-D-galactose biosynthetic gene clusters, and glycosyltransferase gene to produce a range of small molecule glycosides. By applying this metabolic engineering approach, flavonoids, the polyphenolic secondary plant metabolites- Quercetin and Kaempferol were glycosylated to produce Quercetin glycoside and Kaempferol glycoside by whole cell biotransformation. This strategy of in vivo glycosylation offers vast combinatorial biosynthesis potential to produce glycosylated natural products by simple fermentation. Key Words: glycosylation, heterologous overexpression, biotransformation, combinatorial biosynthesis potential.

Genetic variation among the base isolates and monosporidial strains derived from these isolates of Tilletia indica- the causal agent of Karnal bunt (KB) in wheat, was analyzed by morphological, growth behaviors and RAPD-ISSR based molecular polymorphism. Genetic make up of fungal cultures vary among each other. The magnitude of variation in KBPN group is less (narrow genetic base) when compared to the other groups KB3, KB9 and JK (broad genetic base) reflecting that variability is a genetically governed process. The generation of new variation with different growth characteristics is not a generalized feature and is totally dependant on the original genetic make-up of the base isolate generating new monosporidial strains. Thus, it can be concluded that monosporidial strains derived from mono-teliosporic isolate, consists of genetically heterogeneous population. The morphological and genetic variability further suggests that the variation in T. indica strains is predominantly derived through the genetic rearrangements through para sexual means.
